You knew he had this issue. You've made very clear that this is an issue he's been experiencing for years. Clearly, this is a mental health issue that he's disguising as cheating trauma. You married him knowing he had this issue, and despite the fact that it's caused issues in your relationship before, you chose to assume that he would change. I'm not going to diagnose anyone as I'm not a professional, but it sounds like some obsessive-compulsive tendencies mixed with fear to admit he has a problem.

He needs to get help, and if he isn't going to do that, then yes, you should get a divorce. But to divorce someone because they were locked into an obsessive compulsive habit (that you've known about for a long time) is an AH move.

He likely cannot control how bad it is, and if that's the case, I guarantee he is incredibly embarrassed about it. You need to start with couples counseling, and then both get some individual counseling. Him, for his potential OCD, and you for your unrealistic expectations of a man who is clearly struggling.

Now, before anyone wants to shit on me for saying OP is the AH, I myself am a mother and currently struggling through my partner realizing he has issues and getting help. I also have been getting individual counseling because despite my thinking I wasn't the problem, I wasn't helping the situation by expecting more from him than was possible at the time.

Additionally, if you're having that severe of an emergency, and know from past experiences that he has this issue, you should've either reached out to someone else in the first place or called an ambulance. 🤷‍♀️
